Struct TileDescriptor 

pub struct TileDescriptor {
    pub first_row: usize,
    pub has_segment_boundary: bool,
    pub num_complete_rows: usize,
    pub row_ids: Vec<usize>,
    pub is_segment_start: Vec<bool>,
}

Tile descriptor for CSR5 segmented scan.

Each tile descriptor records:

• Whether the tile contains any row boundaries (segment starts).
• For each column within the tile, the row index of the first element.
• Whether each column within the tile starts a new segment.

Fields

first_row: usize

Row index that the first element of this tile belongs to.

has_segment_boundary: bool

Whether this tile has any segment boundaries (row transitions).

num_complete_rows: usize

Number of complete rows that start within this tile.

row_ids: Vec<usize>

For each element position in the tile, the row it belongs to.

is_segment_start: Vec<bool>

Bit-vector: is_segment_start[i] is true if position i starts a new row.
